This Subway asks if it is an allergy or preference when ordering their gluten free buns. If you say allergy they immediately take off their gloves, wash their hands, and put on new gloves. They are careful with how the bun is placed on paper, and they use plastic knives. There is always a risk of cross contamination because the ingredients are out where they are used for gluten containing buns regularly but they do a really great job being as careful as they can be. They also don’t touch any gluten containing subs while your gluten free one is being made.
